Electric vehicle conductive charging system - Part 21-2: Electric vehicle requirements for conductive connection to an AC/DC supply - EMC requirements for off board electric vehicle charging systems

This part of IEC 61851 defines the EMC requirements for any off-board components or
equipment of such systems used to supply or charge electric vehicles with electric power by
conductive power transfer (CPT), with a rated input voltage, according to IEC 60038:2009, up
to 1 000 V AC or 1 500 V DC and an output voltage up to 1 000 V AC or 1 500 V DC.
This document covers off-board charging equipment for mode 1, mode 2, mode 3 and mode 4
charging as defined in IEC 61851-1:2017.
Cables where there is no electronics or no electric/electronic switching are considered as
passive (benign) and are deemed to comply with the emission and immunity requirements of
this document without any need for testing.
This document does not apply to any on-board components or equipment of charging or
power supply systems being part of the vehicles. The EMC requirements for such equipment
are covered by IEC 61851-21-1: 2017.
Compliance with the emission and immunity requirements of this document is verified where it
can be demonstrated that the equipment under test (EUT) meets the respective limits, during
type tests in the measuring arrangement of this document.
Requirements for electric vehicle wireless power transfer (WPT) systems are covered in
IEC 61980 (all parts).

Konduktive Ladesysteme für Elektrofahrzeuge - Teil 21-2: Anforderungen für den konduktiven Anschluss von Elektrofahrzeugen an eine Wechsel-/Gleichstromversorgung - EMV-Anforderungen an externe Ladesysteme für Elektrofahrzeuge

Système de charge par conduction pour véhicules électriques - Partie 21-2: Exigences applicables aux véhicules électriques pour connexion par conduction à une alimentation en courant alternatif ou courant continu - Exigences CEM concernant les systèmes de charge non embarqués pour véhicules électriques

IEC 61851-21-2:2018 définit les exigences CEM concernant les composants ou les équipements des systèmes de charge non embarqués qui permettent d'alimenter ou de charger les véhicules électriques par une source d'alimentation électrique par transfert d'énergie par conduction (CPT ), avec une tension d'entrée assignée, jusqu'à 1 000 V en courant alternatif ou jusqu'à 1 500 V en courant continu, conformément à l'IEC 60038:2009, et une tension de sortie jusqu'à 1 000 V en courant alternatif ou jusqu'à 1 500 V en courant continu. Le présent document traite des équipements de charge non embarqués pour les charges en mode 1, mode 2, mode 3 et mode 4 telles que définies dans l’IEC 61851-1:2017. Les câbles sans composants électroniques ou qui ne subissent aucune coupure électrique/électronique sont considérés comme passifs (faibles). Ils sont jugés par ailleurs conformes aux exigences d'émission et d'immunité du présent document sans qu'aucun essai ne s'avère nécessaire. Le présent document ne s'applique à aucun composant embarqué, équipement de charge ou système d'alimentation faisant partie des véhicules. Les exigences CEM concernant ce type d’équipements sont couvertes par l'IEC 61851-21-1:2017. La conformité aux exigences d'émission et d'immunité du présent document est vérifiée lorsqu'il peut être démontré que l’équipement en essai (EUT ) satisfait aux limites respectives, lors des essais de type effectués avec le dispositif de mesure du présent document. Les exigences concernant les systèmes de transfert d'énergie sans fil (WPT) pour véhicules électriques sont couvertes dans l’IEC 61980 (toutes les parties). IEC 61851-21-2:2018, avec l’IEC 61851-21-1, annule et remplace l’IEC 61851-21:2001. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'IEC 61851-21:2001: a) le présent document ne traite que des essais de CEM plutôt que d’autres essais électriques; b) les Articles 2 et 3 ont été mis à jour; c) les accès, les montages d’essai et leurs limites respectives ainsi que les modes de fonctionnement sont définis de façon plus précise; d) les Annexes A à F ont été ajoutées.

ELECTRIC VEHICLE CONDUCTIVE CHARGING SYSTEM –
Part 21-2: Electric vehicle requirements for conductive connection to
an AC/DC supply – EMC requirements for off-board electric
vehicle charging systems
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC

Publication(s)"). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

ELECTRIC VEHICLE CONDUCTIVE CHARGING SYSTEM –
Part 21-2: Electric vehicle requirements for conductive connection to
an AC/DC supply – EMC requirements for off-board electric
vehicle charging systems
1 Scope

This part of IEC 61851 defines the EMC requirements for any off-board components or

equipment of such systems used to supply or charge electric vehicles with electric power by

conductive power transfer (CPT), with a rated input voltage, according to IEC 60038:2009, up

to 1 000 V AC or 1 500 V DC and an output voltage up to 1 000 V AC or 1 500 V DC.

This document covers off-board charging equipment for mode 1, mode 2, mode 3 and mode 4

charging as defined in IEC 61851-1:2017.
